IMPROVEMENT IN GATE'S.

Specification forming part of Letters Patent No. 215,758, dated May 27, 1879; application filed April 9, 1879.

To all whom it may concern:

Be it known that I, JAMES A. KNICKER- BOOKER, of Maple Rapids, in the county of Clinton and State of Michigan, have invented certain new and useful Improvements in Gates; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side view. Fig. 2 is a side view, showing the gate open. Fig. 3 is a view taken from the opposite side, the gate being shown partly open. Fig. 4 is a cross section, taken through the central posts. Fig. 5 is 'a detail view, in perspective, of the pivoted sliding bar, with its operating mechanism; and Fig. 6 is a longitudinal sectional view.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to sliding gates; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, A represents the gate, which slides between two posts, B B, upon a beam, 0, supported upon two posts, D D, arranged, as shown in the drawings, one on each side of the central posts, B B. The beam or bar 0 slides in a mortise, E, in the post D and upon a roller, F, journaled to the inner side of post B. It is composed of two parts or pieces, one of which, G, slides, as described, while the other part, H, is hinged to the end of the piece G in such a manner as to be capable of being raised to a vertical position, as represented in Fig. 2 of the drawings. The said bar H is hinged to bar G at a point between the posts B B and D, and it is providedwith an extension, H, extending to the post B, which is provided with a groove, I, to accommodate a roller, J, journaled upon the end of the extension of bar H.

The post D is provided with a recess, K, to receive the end of bar H, thussupporting it in such a manner that the gate may rest thereupon when closed. The gate is provided with rollers L L, by which it slides upon the bar G H, the main part of which, G, is provided with a shoulder, M, located at a point between the posts B B and D, the distance between which and the point at'which the part H is hinged to the bar G is equal to the width of the gate.

When closed the gate occupies the position between posts B B D represented in Fig. 1 of the drawings. To open it, it is slid laterally upon the bar 0 in the direction of the post D. When the shoulderMupon said bar is reached the end of the portion G of said bar is slid through the mortise E in post D. At the same time the hinged bar H, which forms a portion of the bar 0, is gradually elevated to a vertical position, as shown in Fig. 2, such movement being accomplished by the roller J traveling in the groove I in post B. To close the gate, the operation is simply reversed.

O is a rail sliding between two of the rails of the gate, and having a hooked end, P, fitting in a recess, Q, inthe post D, where it may be secured by a catch, B. When it is desired to so adjust the gate as to prevent the passage of horses and cattle, but so as to admit hogs, sheep, &c., the end of the rail 0 is secured in the recess Q, and the gate slid open until the shoulder M is reached. The rail 0 and bar H will thus remain closed for the purpose above stated.

Having thus described my invention, I claim and desire to secure by LettersPatent of the United States- 1. The combination of sliding beam 0, composed of the posts BB and the bar G, having shoulder M, and hinged bar H with the gate A, arranged to slide upon said beam, substantially as and for the purpose herein set forth.

2. The combination of the posts B B, the former having groove I and roller F, post D, having mortise E, and sliding beam 0, composed of the bar G, having shoulder M, and hinged bar H, having extension H, provided with roller J, with the gate A, arranged to In testimony that I claim the foregoing as slide upon said beam 0, substantially as and my own I have hereto affixed my signature in for the purpose herein set forth. presence of two witnesses.
